Other than that, the other differences are more subtle – the ace 2 has a button at the side of the screen for example, and the ace 2’s touchscreen display is ever so slightly darker than the ace 3, although it doesn’t impact use. It also took a half an hour to sync with our app, where the ace 3 was ready to go in minutes. Our only gripe is that the Fitbit chargers aren’t universal, which would make life a whole lot easier. We found ours tended to last three or four days before it needed recharging, but you can get more battery life if you don’t use the animated clock faces. The two biggest differences are the look – the ace 2 is slightly squarer – and the battery life, which is up to five days for the ace 2. The ace 2 is pretty similar to the ace 3 (£69, .uk), so it’s a good option if you want to shave a bit off the cost. It’s also water resistant to 50m which is great for swimming lessons, but equally reassuring for everyday spills. The ace 3 promises up to eight-day battery life – although ours tended to need recharging after around five days, which is no surprise given the number of times our tester touched the screen to check the number of steps he’d done. The all-day steps tracker was easily the most popular feature with our tester, and we definitely noticed an increased desire to be active from the first day he wore it – if only to beat his sister’s daily step goal. None of Fitbit’s child-friendly models track heart rate, so you’ll need to move up to an adult model if that’s a must-have. Our tester watched as a rocket, which began grounded, went further into space the more steps he walked.įeatures-wise the ace 3 can track sleep, set bedtime reminders and morning alarms, and has timer and stopwatch features for races. The clock face is easy to read, and kids can choose an animation that comes to life as they hit their goals – which you set in the Fitbit app on your phone. The Fitbit component itself pops out of the strap easily, and you can buy straps separately if your kids fancy a change. The ace 3 comes in blue with green details, black with red details, and a special-edition Minions version in yellow. Our eight-year-old tester found it comfy to wear every day. Firstly, the look and feel of the ace 3 is pleasingly curvy, with a very light and slim silicone strap that’s designed to fit small wrists. The ace 3 brings with it a few improved features. It’s no surprise that Fitbit’s newest offering for kids takes the crown here.
